O youth! You are like a person traveling in the desert while possessing priceless jewels that he intends to sell in the land of reward, so beware of falling into the trap of your treacherous desire so you do not end up selling what you have for less than of what it is worth. Otherwise, when you reach your destination and see those who made great profits, you will cry for your loss and say, ‘Oh how great is my regret over what I neglected in regard to Allah. However, regret shall never restore what has been missed.
—Ibn al-Jawzī [d. 597H/1201CE]
